The DfT has developed software to produce Census Journey-to-Work matrix extracts for use in base year matrix building. The software produces trips by mode in a production and attraction format suitable for transport modelling. The users define their zoning system, specifying each zone in terms of one or more 2001 Census regions, counties, districts or wards. Appropriate factors are applied to convert from the 'usual journey to work' in the Census to an estimated number of trips by each mode in the selected year, split by household car ownership if required.
Sources:
The main source of data is currently the 2001 Census data and the National Travel Survey
Accessing Data:
The Census Journey to Work Trip Matrices can be accessed from Peter Davidson Consultancy.
Cost:
The software is maintained and distributed by Peter Davidson Consultancy and is available to all public authorities. Private sector users will need to negotiate royalty payments with ONS.
